Even though that sempron is based on the phenonII it's still a pritty poor cpu
For about £30 you can get a slightly older Athlon x2 which would be far better.
That case is also really nasty, You can get some quite nice very cheap cases.
Infact going through ebuyer I just spotted this

Nice layout, much better hex fan grills, 120m fan mounts, black internals.
For £25 that looks surpriseing good.
I'm almost tempted to get one just to see what it's like.
Just checking fleabay compleated listings, you should be able to get a 2nd hand 19" monitor for around £50-60 with p&p
oh and 120mm fans will be under £5
Someone has got 2 thermaltake 120mm fans currently at £0.99
